Percutaneous coronary stenting in guide-induced aortocoronary dissection: angiographic and CT findings.

We report here on a case of accidental aortocoronary dissection that occurred during the engagement of a guiding catheter. This resulted in an antegrade dissection into the right coronary artery, and a retrograde extension of the dissection into the Sinus of Valsalva and the ascending aorta up to the aortic arch. It was successfully treated with a stent deployment at the RCA ostium; this restored optimal coronary blood flow and there was a complete resolution of the aortic dissection as was documented by coronary angiography and the follow-up CT scan.
